In this utility model, anti-pinch activate switch 4 is magnetic switch, and anti-pinch closing switch 5 is magnetic switch.
In this utility model, air inlet pipe 111 is a flexible hose.
Operation principle of the present utility model is as follows:
At closing time, compressed air (0.4～0.8Mpa), by air inlet speed governing joint 1, enters inlet chamber 6 to car door,
Acting on piston 7 to be allowed to move right, the air of promotion discharge chamber 13 is through cushion chamber 10, then passes through aerofluxus
Speed governing joint 3 enters in outside atmosphere, in this course when cushion collar 8 moves to cushion chamber 10, and row
The air of air cavity 13 by buffering aperture 9 through cushion chamber 10, then outside being entered by speed governing exhaust joint 3
In portion's air.
In whole car door motor process, if car door runs into barrier, cause piston 7 speed to reduce, cause
The gas pressure intensity of discharge chamber 13 diminishes, and this pressure signal is by being arranged on connection separate gas passway 12
Detection device 11 at cylinder back cover is converted to faint millivolt analogue signal, by high power instrument in control device 2
Table amplifier amplifies this millivolt of analogue signal, by A/D conversion digital signal, is transported to Single-chip Controlling
Device CPU, the thus special algorithm of internal processes, it may be judged whether anti-pinch, the sensitivity of anti-pinch is completely by journey
Sequence controls and sets.
Arranging magnetic switch 4 as anti-pinch device anti-pinch activate switch, arranging this switch purpose is due to car door
After mechanism fully opens, in the range of just starting the angle (15 °) closed the door, car door mechanism running resistance
Greatly, cause piston 7 speed to reduce, cause detecting device 11 and produce signal, produce misoperation.Regulate this
Switching to a correct position, when the angle when car door runs to car door opening is more than 15 °, piston 7 is transported
Row steadily after restart magnetic switch 4 and output signal to control device 2 and open work.
Magnetic switch 5 is set and turns off switch as anti-pinch device, it is therefore an objective to during piston 7 rundown position,
Vent amount is decreased to not aerofluxus, causes the gas pressure intensity of discharge chamber 13 to diminish, and can cause detecting device
11 produce signal, produce misoperation.
Detection device 11 is arranged on the gas pressure that separate gas passway 12 purpose is accurate response discharge chamber 13
By force, if being arranged at aerofluxus speed governing joint 3, when piston 7 moves to buffer position, by buffering aperture 9
Restriction, capacity reduce, cause detect device 11 produce error signal.If forcing disconnected anti-pinch, attenuating is closed
Door effectively anti-pinch scope.
The above is only preferred implementation of the present utility model, is not limited to this utility model, should
When pointing out, for those skilled in the art, without departing from this utility model know-why
On the premise of, it is also possible to making some improvement and modification, these improve and modification also should be regarded as this utility model
Protection domain.
